    摘要: The present invention provides a highly glycosylated iduronate-2-sulfatase enzyme comprising an iduronate-2-sulfatase polypeptide with at least 5 kilodalton (kDa) more sugar than iduronate-2-sulfatase purified from a natural source, e.g. human liver. The present invention also provides an enzymatically active polypeptide fragment or variant of such a highly glycosylated iduronate-2-sulfatase. The present invention further provides an isolated nucleic acid encoding iduronate-2-sulfatase, as well as an expression vector, a host cell and a method for producing the present highly glycosylated iduronate-2-sulfatase enzyme. In one embodiment the present invention is directed to a method for producing a glycosylated iduronate-2-sulfatase enzyme which comprises culturing a host cell containing a nucleic acid encoding an enzymatically active iduronate-2-sulfatase polypeptide wherein the host cell glycosylates the polypeptide to a greater degree than a native iduronate-2-sulfatase polypeptide expressed by a natural human liver cell.
